Figure 14 is a perspective view of a container bottom formed with theband saw attachment.

Referring now to the drawings in detail, it will be seen that there isillustrated a conventional type of band saw which is referred to ingeneral 'by the reference numeral lil. Arnon other details, the band sawit includes a frame 12 which has mounted thereon for pivotal movement bymeans of a transverse shaft 1477a baud saw table 1.6. The table 16 isselectively tilted by a tilting mechanism carried'by the frame 12. Theband saw 1@ also includes a band saw blade Zll which is disposedtransversely of the. table 15.1 Inasmuch: as the other portions of theband saw til play no part in the present invention other than that of.their normal functions, they. will not be described in more detailhereinafter.

Referring now to Figure 13' in particular, it will be seen that thereis, secured to the table 16 along one side edge thereof, an angle,memberZZ. The angle memherZZ includes a vertical flange Zdvvhich issecured to the side edge of the, table 15 in face-to-face relation bysuitable fasteners The angle member 2% also includes an upper horizontalflange 2s WlllCl'l lS disposedahove, the

plane of the table l6 and which is provided with a plurality oflongitudinally spaced fastener receiving openings 39. r V

-Also carriedby theband saw'table 16, butalong the front edge thereof,is an upstanding mounting bracket 32. The mounting bracket 32 'issecured to the front edge of the band saw table 16 by suitable fasteners34 and has the upper part thereof bifurcated to form upstanding legs 36and a central seat 38. 7

The band saw table 16 is further'modified for the purpose of the presentinvention by forming in the side edges thereof adjacent the front edgespaced pairs of threaded bores 49. The purpose of the bores 40 will beset forth in more detail hereinafter.

The present invention includes an auxiliary table 42 which is slightlysmaller than the band saw table 16.

The table 42 includes a front edge 44 which has opena ing there'throughan elongated longitudinal slot 46. The

slot 46 terminates in a central band saw blade receiving opening 48.

The auxiliary table 42 also includes side edges 50 and 52. Extendingnormal to the side edge 52 and extending between the side edge 52 andthe opening 48 is a seen that there is illustrated a slide member whichis referred to in general by the reference numeral 60.

The slide member 60 is of inverted T-shaped cross-section which conformsto the cross-section of the guideway 54. Formed 'on one end of the slidemember 60 is a handlemember 62 to facilitate the positioning of theslide member 60 with respect to the auxiliary table 42. Se-

lcured to the underside of the slide member 60 immediately adjacent thehandle member 62 is a stop block 64- The opposite end of theslidejmember 60 isprovided with; an upstanding pointed pivot 66 whosepur-' pose'will be set forth in moredetail hereinafter.

' In order that the auxiliary table 42 may be mounted" on the band sawtable 16, there is'provided alongitudinally extending track 68 (Figs. 7and which is disposed closely adjacent the side edge 50" and whichoverliesthe band saw table 16. The track 68 is carried and extendingoutwardly therefrom is a pair .of longitudinally spaced guide members74.

ment of the auxiliary table 42 longitudinally of the band saw table 16.

In order to determine the positionof the auxiliary the band saw table 16with the grooved collar 86 being received in the mounting bracket 82 andthe attaching bar 70 overlying the angle member 22. The attaching bar 70may then be secured to the angle member 22 by means of the fastener 72,after which the auxiliary table 42 is ready for use.

In the use of the auxiliary table 42 and the components carried thereby,a square block, such as the block 92 illustrated in Figure 5, iscentrally mounted on the pivot pin 66. After the band saw table 16 hasbeen tilted to the desired angle, as is best illustrated inFigure 6, theauxiliary table 42 is adjusted with respect to the band saw blade forcutting the desired diameter circle. Then, the slide member 60 is slidinto the auxiliary table 42 to start'the cut with the band saw blade 2%.The inward movement of the block 92 is limited by engagement of the stopmember 64 with the side edge 52 of the auxiliary table 42. Afterthe-block 92 0 rotated about thepivot pin 66 to cut an external frustobyan elongated mounting bar 70 which overlies .the flange 28. of the anglemember 22 and is secured thereto by suitable fasteners72. Secured to theside edge The guide members 7 .74 are slidably'supported on the track 68to limit move table 42 withrespect to the band saw blade 20, there iscarried by the guide members 74 suitable pointers 76. The pointers 76cooperate with gauges or scales 78 which are carried by the attachingbar 70. a

Inorder to facilitate shifting and positioning of the auxiliary table 42with respect to the :band saw table 16, there is carried by'the forwardedge 44 of the auxtable 42 a nut member 80. The nut member 80 it ismerely necessary'to' seat the auxiliary table 42 .on

conical surface of the desired diameter. The'outer shavings removed fromthe block 92 are then moved off the auxiliary table 42,.and the block 92is withdrawn. Next, through the use of the feed screw 84, the table42 ismoved inwardly to form the next. desired cut, 'After this has beenaccomplished, the slide member 60 is again moved toward the band sawblade 20 to start the band-saw blade'in the block 92. After the slidemember 60 has been pushed all the way'in, the block 92 is again rotatedso as to cut therefrom a frusto-conical member 94 which is bestillustrated in Figure 1. The

The frusto-conical memas a result of the initial cut by the band sawblade '20.

These opposed end portions 96 may be secured togethe by glue or otherdesirable securing means.

'After a first frusto-conical member 94 ,has been cut from the block 92,the process is repeated 'until a plurality of such frusto-conicalmembers 94 have been formed. The additional frusto-conical members 94will 'be of a smaller diameter than the original ones, and

they will berof such a' naturewhereby'they may 'beconveruently nestedfor storage purposes. After the sizeof the block 92 has been greatlyreduced, the end result fwlll be a tapered plug, such as the plug 98 ofFigure 4. The p1ug98 can be utilized in ship repairwork and othertypical uses. a

In order to'form a containerfrom the frusto-conical member 94, it isnecessary that there be provided a bottom. Suchia bottom is bestillustrated in Figure 14- In.ord.er to form the bottom. 100, it isnecessarythat the auxiliary table-.42 be shifted with respect to theband saw table 16. in the manner best illustrated in Figure 11. .At thistime,':the front edge 44 becomes a side. edge, and the side edge'52becomes the front edge,

theauxiliary table 42 being rotated from its position iofFigure 7. Theauxiliary; table 42is centered with Q a respect to. the band sawbladei20, and. the .band saw 7 E table 16 and issecured in that positionby suitable clamps 102 which extend over the'rearv portion'of the band.saw table 16 and that portion of the auxiliary table 42'which nowdisposed at the rear of the band saw table 16. 70

When the auxiliary table 42 is in the position of Figure 11, the bandsaw table 16'is ,in its hon'zontalpositio'n; :I'hen, a board from whichthe bottom 100 is to be'formed 11s placed-on the pivot pin 66. .The'slide member- 60 is then moved into the guideway 54 until an edge' ofthe board- (not. shown abuts the band's'aw blade 20.":The

ass /pea board should be positioned on the pin 66 so that the distancefrom the edge abutting the band saw to the pin 66 is the radius of thebottom 100 to be cut. Theboard is then rotated about the pivot pin 66 tocut the bottom 100. mg a board of an odd size or dimension.

In order that a frusto-conical member, such as the member 94, may havethe ends thereof cut off square, there is provided a cut-off assemblywhich is referred to in general by the reference numeral 104 (Figs. 7, 8and 9). The cut-off assembly 104 includes a pair of brackets 11% securedto opposite sides of the band saw table 16 by means of fasteners 108passing into the threaded bores 40. The fasteners 1118 are so positionedwhereby the brackets 106 are mounted for pivotal movement. Secured tothe upper portions of the brackets 106 by suitable fasteners 110 aredepending legs 112 of support arms 114 which are disposed at oppositesides of the .band saw table 16. The support arms 114 have secured tothe underside thereof a base 116. The base 116 normally rests upon theauxiliary table 42 when the cut-ofi assembly 104 is in an operatingposition.

Extending between the support arms 114 is a pair of longitudinallyspaced rails 118. Mounted on the rails 118 is a pair of transverselyspaced support bars 120. The support bars 120 are connected together bya cut-elf table 122. The relationship between the support bars 120 andthe rails 118 is such that the cut-oif table 122 may be reciprocatedtransversely of the saw blade 20 and the band saw table 16. I

In order that a cylindrical or frusto-conical member may be mounted onthe cut-off table 112, there is provided a cradle formed by a pair oftransversely spaced, longitudinally extending members 124. In order tofacilitate reciprocation of the cut-off table 122, there is provided asuitable handle 126. As is best illustrated in Figure 9, thefrusto-conical member 94 to be cut off to the desired length and havethe ends thereof squared is placed on the cut-oif table 122 between themembers 124. At this time, the frusto-conical member 94 is disposed atone side of the saw blade 20. The cut-01f table 122 is then movedtransversely of the band saw table 16 to perrnit the band saw blade 20to cut off the end portion of the frusto-conical member 94.

As is best illustrated in Figure 7, the cut-off assembly 104 may bepivoted to an out-of-the-Way position with respect to the auxiliarytable 42. Thus, the frusto-conical members 94 may be first formed andthen cut off to the desired length and squareness by merely flipping thecutofi" assembly 104 into the position illustrated in Figure 8.

After the frusto'conical members 94 have been cut off to the desiredheight, they are provided with one of the bottoms 100. At this time, theopposed ends 96 are suitably glued together. The completed container maybe retained in this form, in which case, it will have the sameappearance as that of the frusto-conical member 94 in Figure 1. On theother hand, if desired, the frustoconical member 94, which forms thebody portion of the container, may be reinforced by suitable straps 128.The straps 128 may be of the type utilized in strapping boxes andpackages.

Referring now to Figure 3 in particular, it will be seen that there isillustrated a modified form of container which is referred to in generalby the reference numeral 130. T he container 130 includes a body portion132 formed of one of the frusto-conical members 94. While it has notbeen so illustrated, the container 130 also includes a bottom member109. Further, the container 130 includes a top 134 which will be formedin the same manner described above with respect to the bottoms 100.

In order that the container 130 may be conveniently carried, there ispassed through diametrically opposite openings 136 formed in the upperpart of the body portion 132 a flexible bail 133. The ends of the bail133 are in the form of knots 14%. The top 134 is also provided with Ifdesired, the scale 58 may be utilized in positionsuitable openings 142through which intermediate portions of the bail 138 pass. It will bereadily apparent that when the bail 138 is grasped to carry thecontainer 130, the bail 133 will retain the top 134 in position. Also,when the bail is not in use and it is desired to open the container 130,the bail 138 will prevent accidental loss or separation of the top 134from the remainder of the container 130.

While the present invention has been described and illustrated as beingdirected to means for making frustoconical members for use as containersor the like, it is to be understood that the invention is not solimited. By failing to tilt the band saw table 16, cylindrical bodymembers for containers and the like may be formed in a similar manner.

The foregoing is considered as illustrative only of the principles ofthe invention. Further, since numerous modifications and changes willreadily occur to those skilled in the art, it is not desired to limitthe invention to the exact construction and operation shown anddescribed, and accordingly, all suitable modifications and equivalentsmay be resorted to, falling within the scope of the invention asclaimed.
